Joram was often grumpy. 'Same old thing every night...Stupid sheep...boring, boring!' Even when an angel brought great news of the birth of the King, Joram could not believe it was true. But when he went to the stable, something amazing happened to grumpy Joram.
An imaginative story, exploring the idea, what if one of the shepherds in the fields, the night Jesus was born, was a grumpy guy. Pretty cute. I would recommend discussing what is imagined and what is in scripture with the children to whom you read this story.
